Equilateral triangle abc has side length 1. a line is drawn from the midpoint, m, of bc to the opposite vertex a. which of the following is true? check all that apply. am = 1 am = 1/2 am = squareroot 3/2 bm = 1 bm = 1/2 bm = squareroot 3/2

Darius is studying the relationship between mathematics and art. he asks friends to each draw a “typical” rectangle. he measures the length and width in centimeters of each rectangle and plot the points on a graph where x represents the width and y presidents the length. the points presenting the rectangles are (6.1, 12.0) (5.0, 8.1) (9.1, 15.2) (6.5, 10.2) (7.4, 11.3) and (10.9, 17.5). which equation could darius use to determine the length in centimeters of a “typical” rectangle for a given width in centimeters
